I can't fault this Riad (save to say that the rooms would be better painted in lighter colours (just my opinion) and it was a bit too "English" for my liking (!)): it was very comfortable, the staff were charming and the food was great. (However, happily, I can say the same about all the places I stayed in in Morocco!)
I just think this Riad is seriously overpriced. I paid a third of the price at the other Riad we stayed in in Marrakech (very close by) and have to say the other one had the edge. Can't really see what the extra £90 a night price tag at Riad Cinnamon got us??
I didn't choose Riad Cinnamon - I spent my last two nights in Morocco with a group of friends and someone else (with deeper pockets!) did - and nor would I. While I have no complaints about it, I would much rather stay at an equally as good Riad, and spend the extra $$$ in the souks! :)
